I would still say the air is docile, but right near the tiles the drift was
fairly bad. Of course most people aim to stay below the curtain rod
(~115-120 feet) which is much safer. I think the drift at both the east
and west ends of the floor was similar with models slowly moving toward the
windows for most of the day. If you launched toward the center of the
floor you could generally avoid steering as the model wouldn't make it all
the way to the wall. I didn't steer my F1D on either of my official
flights (granted my longest was only 27) because I stayed under the curtain
rod and launched far enough away from the wall of windows. If you want to
use all 145 feet of ceiling you'll probably need to steer several times.

If the center scoreboard wasn't such a mess I would have been launching in
the center bay between the curtain rods where I think the drift was fairly
neutral. I'm hoping the scoreboard will be raised to the ceiling without
curtains around it next year.
